Optimization of Machining Parameters for Turned Parts Through Taguchi’s Method

The objective of the study is to achieve minimum requirement of radial force during machining of turned parts. This analysis presents the influence of process parameters (nose radius, cutting speed, feed rate and depth of cut) on the radial force as a response variable. For experimentation, an L18 Orthogonal Array (OA) of Taguchi design of experiment is used. EN-16 steel alloy is used as work material because this material has a wide range of applications in automotive industries etc. Carbide cutting inserts are used during experimentations. Furthermore, the analysis of variance (ANOVA) is also applied to find out the most considerable factor. The entire analysis work is carried out using Minitab-16 software. The optimal setting of parameters is: 3rd level of cutting speed, 1st level of feed rate and 1st level of depth of cut. Depth of cut is most significant factor and nose radius is insignificant factor. Finally confirmation experiments are done to verify the optimal results.
